The AFD adjusts motor speed based on demand to reduce energy
consumption and, as a result, energy costs. The Optimus chillers have
cooling capacities ranging from 150 to 430 tons, making them
economical cooling solutions for most buildings, including
high-occupancy schools, hospitals and hotels.

“The Optimus water-cooled chiller delivers up to 39 percent better
energy efficiency than the ASHRAE 90.1 standard requires,” said Rolf
Paeper, applied products business leader at Trane. “That level of
efficiency surpasses a number of similarly sized competing centrifugal
chillers, making it a cost-effective solution for many customers.”

Trane Tracer™ controls allow building owners to
precisely regulate system performance for increased efficiency and
reduced energy consumption. The Optimus chiller can control water
temperature variance within 0.5°F (0.3°C). This level of precision
enables the Optimus chillers to manage industrial or low-temperature
process cooling and humidity in critical applications. The chiller can
produce temperatures as low as 10°F (-12°C) for quick-freezing
applications, like ice rinks. When operating in heat-recovery mode,
the Optimus chiller generates condenser water temperatures as high as
114°F (45.6°C), which can reheat air at variable air volume (VAV)
boxes, preheat air for air handlers and be used for snow-melting processes.

Designed for easy installation, the Optimus chiller can be delivered
through standard 72" x 80" double doors. Its bolt-together
construction allows the Optimus chiller to fit through even smaller
entryways, making it ideal for tight spaces and retrofit applications.

The direct-drive compressor used in the Optimus chiller is designed
with few moving parts to reduce maintenance needs and failure risks.
Under normal operating conditions, periodic tube cleaning and an
annual oil check are the only manufacturer-recommended maintenance
guidelines. In addition, the evaporator is designed to deliver high
efficiencies using less refrigerant, which can help buildings attain
LEED® certification.
